tn:Psovtirtsin-1 tu MACHINES FOR Pssssme 'HATS.

Be it known that I, JOSEPH DE LA 'MAIglof the city of Brooklyn, county of Kings, and Statef New York,

have invented a new and useful Machine for Pressing as well as Blocking Hatsi and I do hereby. declare that' the following is a full and exact description tbereof,`reference being had to the annexed drawingsg in which- Figure 1 is a plan view, the hand-wheel m being removed.

Figure 2, a vertical section.

Figure 3, a side view.

My invention consists in arranging a machine which willdo the blockingas' well as theprcssing byhydraulic pressure introduced into the interior of the hat.

I will commence to describe the machine as it should be for the pressing operation.

Referring to the drawings, a represents 'a metallic platform, having a circular recess, a', in its upperside, of a diameter as large as the largest hat brim-for which the machineis intended. Upon the bottom of this recess a there is secured the brim of an India-rubber hat, b, and upon this brim ofthe rubber hat rests a hollow ring, c, forming an annular chamber, Ywhich receives steam through a pliable hose, e. d is a cylinder, forming an annularsteam jacket, which receives its supply of steam through another pliable hose, d. This cylinder d lis secured to a strong framework, e, which is capable ot' being turned upon pivots, e', by means of a rack segment, attached to the side of frame e7 and a pinion, f', gearing into said segment f, said pinion being turned by a hand-crank. At the lower -partof each side of frame e there is a projection,i g, and a swivel, h, with a set-screw,

h', turningon a pin, c, which is fastened to the platform a, can be turned over said projection, g,.and by turning the set-screw h the cylinder d can be firmly secured to the platform le.. In order to b'e able to turn the cylinder up, these setscrews h must be relieved and the swivels h turned back, as indicated by red lines on one side in iig. 2. Inside of the cylinder d there is a. piston, l, consisting also of a' steam chamber, into which steam can be introduced by a pliable hose, l. The bottom of said piston is shaped so as tolcorrespond withthe tiprof the hat that is intended to be pressed in this machine, and the piston Zeanbe raised up or lowered down according V to the height of the hat by means of a screw, fin, and hand-wheel, m', which runs through the centre of the horizontal brace of frame e. A

The operation of the machine is as follows: The cylinder d is turned backward by the hand-crank, the hat n to belpressed is placed-over the 4Imlia-rubher hat, so thatits brim resti upon the steam ring c, then the cylinder lis brought doivn upon the hat n; the bottom ofsaid cylinder rests thea upon the brim ofthe hat, which is then between two heated surfaces. Then the cylinder is fastened firmly in this position by the swivels L and setscrews h', and finally water is introduced through a pipe, o, in the platform a, and by proper Vhydraulic pressure the Indiaruhber hat is expanded to fill the whole interior of the cylinder, and tlierebyjpress the hat all round against the heated surfaces. For the purpose of blocking hats the cylinder can bea solid plain cylinder, and the bottom of piston Z may b'e perforated, so as to admit steam directly to the hat, in order to keep it soft.

`Haring now fully described my invention, whatI claim therein as new, and desire to secure by Letters Patent, isfl 1. The combination of steam cylinder d, piston l, and steam ring c, for the purpose of aifording heated surfaces to press against.

2. The application of hydraulic pressure into'an expansible India-rubber hat, over which the hat to be pressed is placed.
